How can I display required fields or hide unwanted fields? 

By default all the standard fields are displayed in each module page layout. The customs fields that you create will also be displayed. You can hide some of the standard fields, add new custom fields to the pages and move fields from one section to another section. You can also drag and drop the fields to reorder them.

To show or hide fields

  1. Log in to Zoho Recruit with Administrator privileges.
  2. Click Setup > Customization > Layouts.
  3. In the Edit Page Layout page, drag and drop the Field Labels to/from the List of Removed Fields to hide or show fields.
  4. Click Save.
